drawings, 1 indicates the laterally-movable :arria e of a Fisher type-writer, 2 the nunieraleys thereof, and 3 the casing of our computing device, which is shown mounted in rear of the carriage upon a bar 4. The carriage 1 moves' relative to the computing device for the purpose of presenting a master wheel 5 to'the several number-wheels of the computing device in succession. ,The masterwheel is operatively related te each of the numeral-keys, and upon the depression of a" key to print anu meral said master-wheel is rotated a distance corresponding to the value of the-key,depressed-that is to say,

the decima -space.

the depression of the 1 key will effect a retation of the master wheel the distance of oneunit or increment, while the depression of the 9 key rotates the master-wheel nine units or increments. Conse uently the depression ofan numeral-key wi effect a corresponding a vance of thenumber-wheel with which the master-wheel isengaged. The computing device includes, as usual, a series of denominational numbers, digit carriers, or number-Wheels a, b, c, d, e f, g, h, and 11, designedto register hundre ths, tenths, units, tens, hundreds, thousands, ten thousands, hundred thousands, and millions, the tenthswheel bein of double width to accommodate Each of these wheels is provided upon'its periphery with the di its 0" to 9, inclusive, preferably forme in hundred and t or upon the end faces of the'peripheral teeth, one t of each wheel being observable throng a ma nifying sight-glass 6., extending across t e casing 3 at its upper front corner. (See Fi 2.) Each carrier or wheel is arranged to ma e nine-tenths of a com lete revolution independently of the other wiieels of the series to present its di its successively before the sight-glass. an during its .last increment of movement engages the wheel to the left and moves it a single increment or step,after which the first-named wheel may again rotate independently for nine-tenths o a complete rotation before again advancing the adjacent wheel at the left a single step. Since the wheels of the entire series are related to one another in the manner stated, it follows that mechanical computations in addition may be effected by movm the wheels corresponding in order to the or er of the digits composing the numbers to be added a number 0 increments corresponding to the unitary values of such digits. Thus su pose it isdesired to add four iii'rty-two and two hundred and thirty-four. The ciphers of all of the wheels bein disposed opposite the sight-glass, the whee of the third. orderto wit, the hundreds-wheel' ewill -be rotated four incre ments, presenting the digit f 4 opposite the sightlass, the tens-wheel d of the second orderwi 1 be rotated three increments, and the units-wheel c of the first order two increments or steps. The numerals observable through the glass will now read 432, corresponding t'o'the first number. The second number. two hundred and thirty-four, will now be added by imparting to the third-order wheel 0 two additional increments of movement, to the second-order wheel (I three'increments, and to the first-order wheel 0 four increments, thus causing the numerals presented before the sightass to read 666, the sum' of the two numbers. Since the numerical value of each order is ten andsinc'e each wheel during its last increment of movementwill, as heretofore explained, impart a single increment of movement tothe'next adjacent wheel to the left, it follows that when the number re istered reaches the limit of the numerical va ue of a given order the rotation of the adjacent wheel to the left will effect the registration of a digit of the next higher order. Thus assuming the first-order or units wheel 0 to be given nine increments of movement, causing the presentation of the digit 9 opposite the sightglass, the next or tenth increment of movement will present the 0 on said wheel be fore the sight-openin and by the automatic engagement of the w reel 0 with the wheel (I of the next higher or second order the latter wheel will be moved a single increment to present the digit 1 of the second order before the glass, the resentation ofthe two digits 0 and 1 in the first and second or ers effecting the registration of the number 10.

The transfer or carrying mechanism.-Adjacent to the rear end of the casin 3 is disposed a transverse su porting-r0 8, upon which are independenti y mounted a series of transfer members or levers 9,, one of these levers being arran ed opposite each of the number-wheels Wifi'l the exce tion of wheel a, for which no lever is provi ed. These levers are arranged to 'SWlIlg from the rod 8 in a manner to bedescribed and each is formed with a pointed tailpiece 10, engaged by a swinging detent 11, urged to its en aging positio'n'by a sprin 12 and arrange to yieldingly retain the ever at either limit of its movement. The levers 9 are of irre lar form and each is provided in rear of its ont end with a endent ar'm13, to which is attached in a aterally offset position (see Figs. 22 and 23) a contact-plate 14, having its front end extended between a pair of digitcarriers and its rear end located in one of a series of guide-openings or notches 15 in a guide-bar 16, extending across the casing. (See' Fig. 4.) The front end of each contactplate 14 is arranged to be engaged by a lug or projection 17, preferably having the form of a small late secured to the left-hand side face of each digit-carrier except the carrier t. (See Figs. 4 and 13.) This engagement of the projection 17 with the contact-plate 14 does not occur,however, until the digit-carrier has teeth of the digit-carriers, and thus be permitted to move back ireel y when the carriage is retracted to begin a new line of writing. Neither the actuator 31 nor the depressingplate 32 are elements of the present invention, They are shown and described to emphasize the utility of the vibrator when. the computing device is used as a )art of the type-writer equi' lnent; but it wi l be understood that the vibrator may be operated by other actuating means or manually.

The locating mechanism for the number wheels.1 or the urpose of locating the number-wheels wit accuracy, so that the digits will always be dis'iosed in exact alinement before the sight-glass and for the further pur Jose of preventin reverse rotation of the w eels by frictionafcontact with the transfer-dogs during the elevation of the transfer-levers, we provide what may be termed wheel-locators 33. These locators are in the form of swinging arms mounted upon a transverse rod 34. Each locator is provided with a roller 35, urged upwardly into engagement with the adjacent numbor wheel by a spring 36, located an a spring-casing37 and bearing against a plunger 38, which in turn bears a ainst a depending angular ex-' treinity 39 of the loeator. The roller 35 is of such diameter that when disposed ooposite an interval between two teeth otthe a acent number-wheel its periphery will be engaged by the contiguous outer corners of the teeth. Obviously the rotation of the digit-carrier in either direction will necessarily be acconga nied by the depression of the locetor, an as this depression is resisted. by the spring 36 it will be apparent that the number-wheel cannot be moved except by the application of suffiEfient force to overcome the spring. These locators therefore serve to hold the numberwheels in their accurately-Mined positions. Aside from this retention of the wheels, however, these locators, actually serve to locate the wheels. By reference to Fig. 5 it will be seen that when a wheel is rotated'the adja cent locator is de'iressed to permit the teeth of the wheel to ri e over the roller. As soon, therefore, as the tooth has passed beyond a plane intersecting the axes of the wheel and -roller the tendency of the. locator to move back to its elevated position will serve to complete the movement of the numberwheel, which, however, will be arrested and located by the engagement of thenext succeedin tooth with the roller.

The ocators obviously present more or less resistance to the rotation of the numberwheels, and the illustrated construction therefor co-rnprehends means for easing the number-wheels to decrease the burden imposed upon a key when a series of Wheels are moved in i1nisonas, for instance, in adding l to 99,999. This easing means or locator-depressing mechanism constitutes no part of the present invention but may be briefly do scr bed as follows: A focator-depressing plate 40 is hinged upon a support 41, mounted on the carriage. This plate is urged upwardly to its horizontal )osition b a spring 42, where it is retaine' by shoul ers 43, bearing against the support 41.

The front ends of the loeators 32 are ex tended beyond the front of the casing 3, where they are provided with teeth 44-that is to say, the locators, with the exception-of those provided for the three wheels of lowest order, are so extended, these three wheels being excepted, for the reason that, as heretofore stated, it is impracticable to depress the locators of the two wheels next adjacent to the one being actuated, and as the necessity for depressing any of the locators ceases when the mastemvheel moves out of engagement with the wheel a of lowest order no provision need be made for depressing the locators of the wheels I) and c.

As the carriage moves to the right the locator-depressing plate 40, the ends of which are beveled as shown, rides over the toothed ends of the locators, beginning with the locator of the wheel 11, when the master-wheel is in engagement with the wheel f and successively depresses the locators sufficiently to ease the wheels for the purpose stated. The depression is not sufficient, however, to absolutely prevent the locators from performing their unctions as suchthat is to say, while the rollers 35 are drawn back slightly their retraction is not such as will errnit the jarring of the number-wheels to e eat their disloca tion.

When the master-wheel moves into engagement with the number-wheel of lowest order, it is practicable to entirely depress such of the locators as are extended beyond the front of the casing in order to still further decrease the resistance opposed to the key when an extended series of number-wheels are moved in unison. 'We therefore mount upon the front of the casing a rigid trip-bar 45, having its under corners beveled, as shown, and so located that as the masterwheel advances from the wheel b to the wheel a the locatordepressing plate 40 will ride 'under the tripbar, and thus be swung down or depressed sufiicientl to entirely retract the locators associate. with the wheels (1 to 11, inclusive. As a result of this arrangement the almostprohibitive resistance, which has heretofore aeen opposed to a ke b an extended series of wheels, is minimize and the touch is made comparatively light. y

The means for restoring the transfer-levers to their normal positiona- -When the masterwheel moves beyond the number-wheel of lowest order, the transfer-levers will still remain in their depressed or locked positions, and it is obvious that some means must be provided for returning these lovers to their normal positions before the meeter-vvheel againtraversesthecomputi device,asother- W188 the number-wheels w'ou d remain locked. The present embodimentof this lever-retractmechanism includes a rocker 46, (see Fig. Eb mounted to swing from a transverse-bar 47. and comprising a pair of angular-l sreleted leaves or p ates 48 and 49. The-lief 48 of the rocker is disposed opposite s cam-face 59, formed on eachof the transfer-levers 9 at a point inadvance of its axis. When the transfer-levers, or any of them, are drawn down to'their depressed pos tions, as shown in Fig. 6, their cam-faces nil-are moved close to or in contact with the leaf 48 of the rocker, so that 'vthen the latter is rocked hack the -iransfer-levers will be raised or retracted to their normel'po'sitions. It hes been ointed out that thesprings 12 exert some orce to assist in the downward movement of the isvers, and it will now a pear that these springs similarly assist in t e elevation ofthe levers as soon as the detents 11 are brought into engagement with the up or sides of the.

tail-pisses 1 8 of the levers. he rocker n; is connected to a slide 51, (see Figs. 17 to 21,

inclusive,) whicli extends beyond the frontof the easinggsee Fig. 2) to faciiitetev its actuetion. In t e illustrated use of the totalizer the siide 51 has a beveled extremity 52 disposed for en agemeht by what me. he termed a rocker-s ide aetuatorf"53. e Fi 3.)

This actuator is formed with an incline side 7 face 54 and an inciined bottom fee-e oosndis carried at the end of an angular arm 56, pivotally mounted on the carriagef Assuming the transfer levers, the rocker, and the rocker-slide to be in the positions indicated in Figs. 2 and 6, the retraction of the carriag'e'to the left will present the inclined side face 54 of theactu'etor 53 to the inclined end v52 of the right, the actuator 53-w1ll not move the $5 the slide 51; As the movement of the carriage continues, the slide will be forced beck, thusswinging the rocker 46 to the dotted-line position in Fig. fi for the purfpose of effecting theelevation' or retraction o the transfer-lever.

In the present embgglignent ofjhe Invention this means iiieludes'esvi'inging one having an angular upper end. 87,". pivotaiiy: moonted of the casing 3. t its upper end the arm 86 is provided at a point in advance of its axis 7 gmon a heermgeserew 88, rojectingfrom a 81 e wall a in 89, disposed to be engaged by the inner or out an of the latchever 83, the lower end'of thearm being connected, as by a link' 90, with the inner or rear end of the rockerslide 51. (See Fig. 21.) Assumin that the ENS are now in the positions inchcated in ll lines in Fig. 17 and that it is desired to reset the computing device, the end ofthe resetting-lever is grasped. Thisaction serves to swing the latch lever from the full-line position' in Fig. 17 to the dotted-line position therein indicated, thus causing the flange 82 on the latch-lever to swing the latch 77 out of enga ement with the casing and de ressing the out end of the latch-lever, which, by

reason of its engagement with the lug 89 on the arm 86, swings the latter for the purpose of retracting the rocker-slide 51 and operating the rocker 46, which in turn effects the elevation of the transfer-levers 9 to release the number-wheels. The arts will now be in the positions indicated'm dotted lines in Fig. 17 and the resetting-lever and numberwheels having been released the lever may be swun up for the purpose of resettin the whee s. Of course as soon as the latchever is moved out of engagement with the arm 86 by the elevation of the resetting-lever 75 the spring 59 will restore the slide 51 and the arm 86 to their normal positions.

When'the resettinglever reaches the 'position indicated in full lines in Fig. 18, the resetting-cams will have moved around ninaincrem'ents, the shoulders 70 of said cams being within one increment of their normal 081;,

tion. As the beaks of the severalpaw s 7,1 are in engagement with these shoulders, it; follows that thewvheels will all be registeri 9 before the sightglass, and the prejec tions 17 on the wheels will therefore be in engagement with the contactlates 14 of the transfer-levers. Therefore uring' the final movement of the resetting-lever before re; storing'the came to their normal positions the wheels will all be moved from 9 to 0 and the transfer-levers will .be carried down and the number-wheels locked the final positions assumed by the parts being indicated by dotted lines in Fig. 18. Before the computing device canbe again operated it is necessary to unlock the number-wheels, and while this may be done by retracting the carriage in the manner already explained it is desired to have the corn uting device comurged u wardl by a spring 93, connected at one en to a xed part and at its 0 posite end to a tail iece 94:, extended from the sup port92. T e block 91 is normally retained y the resettinglever in the position shown in Fig. 17 but when said lever is swung up the support 92 is swung by its spring 93 and the block 91 is moved into engagement with a projection 95 on the arm 86. When in this position, (see Figsr18 and 19,) the up er end of the block 91 is disposed somewiiat above the plane of the lug 89'. If new the resetting-lever, havin reset and locked the wheels, is swung bac: to the position indicated in full lines in Fi 19, it will contact withthe upper end of the block 91 and durv,ing its final movement to its resetting positions will force down the block, thus moving the arm 86, the slide 51, and the rocker 46, and the transfer-levers 9 to the osition shown in dotted lines in Fig. 19. bus the retraction of the resetting-lever sheets the unlocking of the number-wheels b restoring the transfer-levers to their norma positions. As the block moves down, however, with the resetting-lever to effect the described movements of the arm 86. and connected parts it will be swung slightly on its individual axis by reason of the fact that its upper face 96, with which the resetting-lever contacts, is slightly inclined, and this individual movcment of theblock and the swinging movement of the arm 86 will effect the disengagement of the block from the rejection 95. (See Fig. 21.) By reason of t is disengage ment the arm 86, having performed its function, may swing back to its normal position, thus presenting the lug 89 to the inner end of the latch-lever'83 and restoring the slide and rocker to their normal positions preparatory to the inauguration of another computation.

In the present embodiment of the invention the wheels which cooperate with the car- .rying, lockin locating, and resetting mechanismsactua ly carry and exhibit the digits; but it will of course be understood that so far as the invention is concerned it is immaterial whether the digits are carried b Y these wheels or not, since the digits may e carried by other members geared to these wheels in a manner. common in the art. Furthermore, in certain as ects of the invention these wheels are to e regarded as members occu-- pying different denominational positions, irrespective of their form, and for this reason have been designated, broadly, in the specication as denominational members.
